I just tried it out for proxies creation where I am rendering out Individual clips with filenames using source name. In this setting, the timecode from the source clips are used instead of the timeline timecode. The clips used also have synced audio from separate wav files.
Unlike previous versions, each clip is not starting at 0:00 anymore but it is not accurate. I have to look at it more, but each clip seems to be off random times. I tried the open sourced x264 plugin made by Blackmagic, and it's accurate with timecode.
Here are 3 clips I used, tell me if you see the Pattern on why it's off.

On top of this, I noticed some audio rendering issues, I'll make another posting about it. But it's mainly having issues exporting 24bit WAV and channel mapping.
